Product description

The transformer converts high primary current up to 3000 A into standardized secondary current 5 A, enabling safe connection:

  • measuring devices and ammeters

  • protective systems

  • automation and monitoring systems

Thanks to the screw-on design and mounting feet, the transformer is easy to install on a 100 mm diameter busbar without the need to interrupt the circuit.

Advantages

  • High current capacity – suitable for high power lines and loads (primary current up to 3000 A)

  • Standard secondary current 5 A – compatible with most measuring and control devices

  • Accuracy class 0.5S – stable and precise measurement suitable for monitoring and protection

  • Rated power 30 VA – sufficient for connecting secondary devices

  • Easy installation – screw-on window design and mounting feet included

  • Universal use – suitable for distribution cabinets, industrial systems, measurement and protective applications

Recommended use

  • Industrial and commercial distribution cabinets

  • Monitoring of current load and energy consumption

  • Connection of meters, ammeters, protective and automation systems

  • Load measurement and control systems
